I was so confused about all the fasting "rules" at first, not so hard now. I know in my case, I can get so caught up in the "legalities" of why, that it takes focus off God, rather than focusing on God, church attendance, prayer. The rest will come. As far as circumcision, I had it done to both my sons. Not for religious purposes. I started working as aide in a nursing home when I was 16.(I'm still in that field today) Over the years, some elderly men (uncircumcised) were not able to take care of personal hygiene as well as they use to (due to physical, or Alzheimer's type conditions), some families were not so attentive to "private parts" with trying to care for these people. I've seen too many sores that didn't heal from lack of diligent personal care. Some of these sores never healed and caused other problems with these gentlemen. I felt it was a way to help with that when they are at ripe old age, since I won't be there then to see to it if they should need help with their personal hygiene. ( I had partial circumcision done to them, not total). Just my 2 cents.
